Final answer:
A recent study examined the relationship between income inequality and homicide rates in the United States and Canada. The study found that there is a positive correlation between income inequality and homicide rates in the United States, but not in Canada.
Step-by-step explanation:
Income Inequality and Homicide Rates
A recent study examined the relationship between income inequality and homicide rates in the United States and Canada. The study found that in the United States, there is a positive correlation between income inequality (measured by GINI and median income) and homicide rates. This means that as income inequality increases, so does the homicide rate. However, the study did not find a similar relationship in Canada.
So, the correct answer to the question is A. Income inequality is related to homicide rates in the US but not in Canada due to the fact that the income inequality in Canada is negligible.
